VISE.

SPECIFICATION forming part of Letters Patent No. 526,753, dated. October 2,1894.

Application filed January 11, 1894. Serial No. 496.555' (No model.)

To all whom it may concern:

Be it known that I, GoTTLoB SILLER, merchant, a subject of the King of Wrtemberg; and resident of sslingen-on-the-Neckar, in the Kingdom of Wrtemberg, German Empire, have invented certain new and useful Improvernent in a Parallel Vise Adjustable Horizontally on its Guideway, of which the following is a specification.

My invention relates particularly to the manner of adjusting the vise circularly into difierent positions.

In the drawings, Figure 1, is a side elevation, Fig. 2, a similar view of the upper part, and Fig. 3, a similar view of the lower part separated from each other. Fig. 4, is a bottom plan view of the base portion of the upper part. Fig. 5, is an end view of the upper part, and Fig. 6, is a plan View of the lower base portion. Shown in Fig. 3.

On the plate p of the clainp bracket B a having the set screw s is a Vertical screw r,

threaded into the circular boss or projection x. This screw may be turned by the star wheel R thereon and it has a head 7a adapted to fit into the socket e' of the base portion a of the upper part of the vise said base part having the ways or grooves e to receive the star and semicircular edges to fit the circular projection w and to turn thereon in adi justing the vise, for which purpose the star wheel is turned to lift the head 70 from its position shown in Fig. 1 to free it from contact with the edge The upper part of the vise may now be turned to any desired radial position and there fixed by turning the star wheel R again to draw the head 78 of the screw down on the fiange or edge f.

The vise proper comprises the relatively stationary part O on the base a and the movable part O', the slide P of which is guided in the way F formed in the part O, said Way having a centering groove n to receive the guide rib n' on the slide P; The movable part is operated by the spindle s screw threaded at g into the bore b of the part O.

I claim- In combination, the base plate 19 having the circular boss x, the upper portion O having the base part a formed with the socket e', the grooves e and the semi-circular edges to bear on the boss w, the screw passing through the boss and having a head lc engaging the socket e', the wheel on the screw and arrangcd in the grooves e for turning the screw and the movable`` part O' With means for adjusting the same, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing wit-nesses.

GOTTLOB SILLER.
